The company is currently organized into three product category divisions ...
James F. McNulty (U.S. radio engineer) of Automation Industries, Inc., then, in El Segundo, California, an early improver of the many foibles and limits of this and other nondestructive testing methods, teaches in further detail on ultrasonic testing in his U.S. Patent 3,260,105 (application filed December 21, 1962, granted July 12, 1966 ...
The dead zone is approximately 5 mm and there is no flaw detection in this zone. Calibration blocks with side drilled holes as shown in Reference [4] and ISO 10863 used to validate the "dead zone" and sizing accuracy.
A list of methods used to detect flaws in rails: Ultrasound - the most popular method; Visual Inspection - Primarily using cameras to detect broken or cracked joint bars in bolted rail. Liquid Penetrant Inspection (LPI) - used for manual inspection of joint bars and rail ends. Eddy current inspection - great for surface flaws & near-surface flaws
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location.
Flaw detection in steel products; Plate lamination defect inspection; Bonded structure lamination detection [8] [9] Laser weld inspection for automotive components; Weld inspection for coil join, tubes and pipes [10] Pipeline in-service inspection [11] [12] Railroad rail and wheel inspection; Austenitic weld inspection for the power industry [6]
The fluorescent penetrant is applied to the surface and allowed time to seep into flaws or defects in the material. The process of waiting for the penetrant to seep into flaws is called dwell time. Dwell time varies by material, the size of the indications that are intended to be identified and requirements / standards but is generally less ...
Jeremy Dunn (Laser Technology Inc.) developed a police lidar device in 1989, [3] and in 2004 10% of U.S. sales of traffic enforcement devices were lidar rising to 30% in 2006, [1] given the advantages of lidar it appears likely that the majority of current sales are lidar, although sophisticated radar units are still being sold.
